I have a couple of old adtrans my company uses; TA924 2nd Gen and TA924e 2nd Gen. that I wanted to troubleshoot and see if they can be redeployed. My first step was to update the firmware for them but I can't find newer versions to download. I used to be able to just download directly from the adtran website but it keeps redirecting me.
The most recent firmware I have is T900G2A-R13-12-0-E and T900E2A-R13-11-0-E.
Any idea where I can find newer firmware?
